Mitochondrial processes are impaired in hereditary inclusion body myopathy.
Hereditary inclusion body myopathy (HIBM) is an adult onset, slowly progressive distal and proximal myopathy. Although the causing gene, GNE, encodes for a key enzyme in the biosynthesis of sialic acid, its primary function in HIBM remains unknown. To elucidate the pathological mechanisms leading from the mutated GNE to the HIBM phenotype, we attempted to identify and characterize early occurri...
متن کاملHereditary Inclusion Body Myopathy (HIBM2)
Hereditary inclusion body myopathy type 2 (HIBM2) is a myopathy characterized by progressive muscle weakness with early adult onset. The disease is the result of a recessive mutation in the Glucosamine (UDP-N-acetyl)-2-epimerase/N-acetylmannosamine kinase gene (GNE), which results in reduced enzyme function and sialic acid levels. A majority of individuals with HIBM2 are from Iranian-Jewish or ...
متن کاملHereditary inclusion-body myopathy: clues on pathogenesis and possible therapy.
Hereditary inclusion-body myopathy (h-IBM), or distal myopathy with rimmed vacuoles (DMRV), is an autosomal recessive disorder with onset in early adult life and a progressive course leading to severe disability. h-IBM/DMRV is due to mutations of a gene (GNE) that codes for a rate-limiting enzyme in the sialic acid biosynthetic pathway. Despite the identification of the causative gene defect, i...
متن کاملThe Proteomic Profile of Hereditary Inclusion Body Myopathy
Hereditary inclusion body myopathy (HIBM) is an adult onset, slowly progressive distal and proximal myopathy. Although the causing gene, GNE, encodes for a key enzyme in the biosynthesis of sialic acid, its primary function in HIBM remains unknown. The goal of this study was to unravel new clues on the biological pathways leading to HIBM by proteomic comparison. Muscle cultures and biopsies wer...
متن کاملHereditary inclusion body myopathy maps to chromosome 9p1-q1.
Hereditary inclusion body myopathy (HIBM) is a unique disorder of unknown etiology that typically occurs in individuals of Persian Jewish descent. Distinguishing features of the disorder from other limb girdle myopathies include elderly age of onset, ethnic predisposition, and sparing of the quadriceps despite severe involvement of all other proximal leg muscles. Involved muscles demonstrate fi...
